Question: If a person travels from 60° West to 30° East, how many hours ahead or behind will they be? (2023)

Options:

Correct Answer: 6 hours ahead

Exam Year: 2023

Solution:

The total change in longitude is 60 + 30 = 90 degrees. 90/15 = 6 hours ahead.

If a person travels from 60° West to 30° East, how many hours ahead or behind will they be? (2023)

If a person travels from 60° West to 30° East, how many hours ahead or behind will they be? (2023)

Step 1: Identify the starting longitude, which is 60° West.
Step 2: Identify the ending longitude, which is 30° East.
Step 3: Calculate the total change in longitude by adding the absolute values of both longitudes: 60 + 30 = 90 degrees.
Step 4: Understand that the Earth rotates 360 degrees in 24 hours, which means it rotates 15 degrees in 1 hour (360 degrees / 24 hours = 15 degrees/hour).
Step 5: Divide the total change in longitude (90 degrees) by the degrees the Earth rotates in one hour (15 degrees): 90 / 15 = 6 hours.
Step 6: Since the person is moving from West to East, they will be 6 hours ahead.
